Points to the current top of the stack memory area, managing subroutines through PUSH and POP operations. The Flag Register (Status Register)
Interrupts are signals sent by external peripherals to request immediate processing from the microprocessor. When an interrupt occurs, the MPU suspends its current program execution, branches to an Interrupt Service Routine (ISR), executes it, and returns to the main program. Classification of Interrupts
Whether you are preparing a lecture presentation, a seminar slide deck, or studying for university examinations, this guide provides a structured breakdown optimized for creating an 8085 microprocessor PowerPoint presentation. 1. Introduction to the 8085 Microprocessor microprocessor 8085 ppt by gaonkar new
A 16-bit register that holds the memory address of the next instruction to be executed.
Before diving into the specifics of the PPT, it is crucial to understand why the 8085 remains a pedagogical powerhouse. The keyword "new" suggests that learners are looking for contemporary explanations of a classic chip. Points to the current top of the stack
The 8085 is a conventional, general-purpose 8-bit Metal-Oxide Semiconductor (MOS) microprocessor. It is an enhanced version of its predecessor, the 8080A, designed to require less supporting circuitry. Key Technical Specifications
According to Gaonkar's pedagogical breakdown, the instruction set is classified based on functional utility and byte length. Classification by Data Length Classification of Interrupts Whether you are preparing a
A positive-going pulse emitted by the MPU during the first clock cycle ( T1cap T sub 1 ) of a machine cycle. It indicates that the bits on
: Active-low signals indicating memory/IO read and write operations.
At the beginning of a machine cycle, the 8085 places the lower 8 bits of the address on AD0-AD7 and drives ALE high.
